Why scale expansion value after DMaskingNAS where TBS expansion (0.75, 4.5, 0.75)

[lxiongh]

Here your arch of dmasking_f1's stage2

# stage 2
[
    ["ir_k5", 24, 2, 1, _ex(5.4566), IRF_CFG],
    ["ir_k5", 24, 1, 1, _ex(4.7912), IRF_CFG],
],

where expansion is not the value from (0.75, 4.5, 0.75), so how to scale it and why? Thanks!

This is because the expansion ratio in the search space is based on the maximum available #Channels in the search space, while the one in the arch def is based on the real #Channels. The actual number of dw channels can be obtained from the model builder.
